What to Do When African茉莉 Leaves Become Soft and Droopy
African Jasmine is loved for its elegant posture and fragrant flowers, but it often faces the problem of soft and drooping leaves during maintenance. This article combines 10 years of gardening experience to systematically analyze 5 key points for treatment, using cause analysis and practical solutions to help your Jasmine regain its vitality.
Wilting Leaves Due to Insufficient Light
Light Demand Characteristics
African Jasmine is a strong sun-loving plant, requiring more than 6 hours of direct sunlight per day. Long-term exposure to a light environment below 3000 lux inhibits photosynthesis, leading to cell dehydration and a decrease in leafstalk support.
Seasonal Supplemental Lighting Plan
Use full-spectrum plant lights in spring and winter to maintain a light intensity of 5000-8000 lux. Rotate the pot regularly on a southeast-facing balcony to avoid uneven light exposure on one side.
Freezing Injury Response Triggered by Sudden Temperature Changes
Temperature Critical Threshold
The optimal growth temperature is between 18-28°C. When the environmental temperature is below 10°C for 48 consecutive hours, the permeability of the leaf cell membrane changes, resulting in dehydration and wilting.
Winter Protection Measures
In northern regions, it is necessary to build a double-layer insulated shed in advance, using a combination of PE film and non-woven fabric. In rooms with radiant floor heating, use a humidifier to maintain a humidity of 40-60%, avoiding heat radiation damage.
Root Damage Treatment Plan
Identifying Standards for Rotting Roots
Healthy roots are milky white and elastic, while rotting roots turn brown and emit a sour smell. When more than 1/3 of the roots are necrotic, immediate surgical treatment is required.
Potting Operation Specification
Use a mixture of sterile perlite and peat soil (3:7) at 121°C. After pruning the roots, soak in carbendazim (1:800) for 30 minutes, then let it dry in the shade for 12 hours before repotting.
Complementary Maintenance Techniques
Water Management Tips
Follow the "dry-wet" principle and insert a bamboo skewer to check the moisture level 2 cm deep. In summer, combine with foliar spraying, using a misting device to complete the process before 10:00.
Nutrition Supplement Cycle
Apply a water-soluble fertilizer with N-P-K = 20-20-20 every 15 days during the growing period, and add phosphorus and potassium (0.2% concentration) during the flowering period. Stop fertilizing in winter.
Through light control, temperature management, and root repair, a three-in-one treatment plan combined with scientific daily maintenance can restore 90% of African Jasmine to an upright state within 2-3 weeks. It is recommended to clean the leaves and test the substrate monthly to establish a preventive maintenance system.
